An Order of Magnitude (abbreviated to OoM) is a measurement of how many times you need to multiply ten by itself to get to a number. Using logarithms, you can instead see what you need to raise ten to the power of, to get non-integer Orders of Magnitude.

## In Egg, inc. Edit

In Egg, inc., the Farm Value is measured in orders of magnitude. This allows for easier comparison, because 1036 and 1042 are easier to compare than 1,000,000,000,000,000,000,000,000,000,000,000,000 and 100,000,000,000,000,000,000,000,000,000,000,000,000,000. With Orders of Magnitude, you don't have to painstakingly count the zeroes, you can just say, '42-36=6, so the second number is 106=1 million times the first!'

## In Science Edit

When comparing extremely large things like stars or extremely small things like bacteria, if there are hundreds of billions of bacteria in a human or trillions of stars in the galaxy or septillions of atoms in a gram of water (6.02214085774×1023), it gets confusing to count the zeroes every time you want to know the exact size of an extremely large or small number, so scientists use Orders of Magnitude for those.

## Calculation Edit

To calculate a number in OoM, you use the equation, log10(number). A logarithm is like saying, 'How many times do I need to multiply the base number (the little one at the start) by itself to get the second one?', and is symmetrical with an exponent ('What do I get when multiply this number by itself this many times?') or a root ('What do I multiply by itself this many times to get this number?'), and there's an idea to remove all of these symbols and words and use a triangle instead.
